News: Ryu (back) threw a bullpen session Monday and will need another session and a simulated game before the club considers having him appear in a game, Eric Stephen of True Blue LA reports.

Impact: At this point, Ryu should be available for the start of the season barring a setback. The Dodgers may have to shuffle the order of their rotation slightly depending on how Ryu works his way back into the schedule.

Impact: The left-hander emerged from Tuesday's bullpen session with some mid-back tightness, but Ryu said he thought the issue was not serious, and a subsequent MRI was returned negative. He was cleared to resume throwing on flat ground Friday, and it looks like the issue will indeed end up delaying Ryu just a few days, as he suggested would be the case.

Impact: The Dodgers held Ryu out of workouts again Thursday after the lefty experienced some mid-back tightness following Tuesday's bullpen session. However, Ryu has expressed confidence that the issue is not serious, and the results of the MRI suggest that is indeed the case. It's still uncertain when Ryu may return to elevated ground, but he thinks the injury will push his schedule back "a few days at most."

News: Ryu is confident that his back issue is not serious, Dylan Hernandez of the Los Angeles Times reports.

Impact: Ryu is currently fighting through a bout of mid-back tightness, which surfaced following a bullpen session Tuesday. The lefty continues to downplay the severity of the ailment, saying that he expects to return to mound work within a matter of days, but it still seems like something that could affect Ryu's availability for the start of Cactus League action.

News: Ryu did not participate in in the Dodgers' workout Wednesday due to "mid-back tightness" following a bullpen session Tuesday, Bill Plunkett of the Orange County Register reports.

Impact: Ryu is aiming for 200-plus innings in 2015, and the mid-back tightness shouldn't prevent him from doing that assuming it doesn't turn into anything more serious. Still, it's worth monitoring in case something more does come of the situation. On the plus side, Ryu hasn't experienced any issues with his shoulder, which caused him problems late in the 2014 campaign.
